java - 通过可执行 JAR 从 cmdline 执行 Cucumber 测试，无需 Maven

Question

以下是执行的步骤:

第 1 步:基于this ，我使用 maven-shade-plugin 构建了一个独立的 jar，其中包含所有依赖项。

pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.2</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
                <testSourceDirectory>${basedir}/src/main/java/</testSourceDirectory>
                <testClassesDirectory>${project.build.directory}/classes/</testClassesDirectory>
                <reportsDirectory>${project.build.directory}/test-output/${timestamp}</reportsDirectory>
            </configuration>
        </plugin>
        <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/executable-jar.html -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <!-- https://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html -->
                        <shadedArtifactAttached>true</shadedArtifactAttached>
                        <shadedClassifierName>standalone</shadedClassifierName>
                        <transformers>
                            <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html -->
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>runners.RunCukesTest</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

向运行器类添加了 main() 方法，并根据 this 传递了 cmdline 参数。 , this ，和 this .

RunCukesTest.java

package runners;

import cucumber.api.CucumberOptions;
import cucumber.api.SnippetType;
import cucumber.api.cli.Main;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = { "src/main/resources/features" }, glue = { "steps" }, tags = { "not @ignore" }, plugin = {
        "pretty" }, monochrome = true)
public class RunCukesTest extends AbstractTestNGCucumberTests {

    public static void main(String[] args) {
        System.out.println("Begin running tests...");
        Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });
    }

}

第 2 步:尝试运行可执行 JAR。

λ java -jar project-xyz-1.0.0-standalone.jar
Begin running tests...
Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features
        at cucumber.runtime.io.FileResourceIterator$FileIterator.<init>(FileResourceIterator.java:63)
        at cucumber.runtime.io.FileResourceIterator.<init>(FileResourceIterator.java:28)
        at cucumber.runtime.io.FileResourceIterator.createFileResourceIterator(FileResourceIterator.java:14)
        at cucumber.runtime.io.FileResourceIterable.iterator(FileResourceIterable.java:19)
        at cucumber.runtime.model.FeatureLoader.loadFromFeaturePath(FeatureLoader.java:112)
        at cucumber.runtime.model.FeatureLoader.load(FeatureLoader.java:48)
        at cucumber.runtime.model.FeatureLoader.load(FeatureLoader.java:30)
        at cucumber.runtime.FeaturePathFeatureSupplier.get(FeaturePathFeatureSupplier.java:22)
        at cucumber.runtime.Runtime.run(Runtime.java:68)
        at cucumber.api.cli.Main.run(Main.java:26)
        at cucumber.api.cli.Main.main(Main.java:8)
        at runners.RunCukesTest.main(RunCukesTest.java:17)

它读取 runner 类中的 main() 方法，但抛出

Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features

更新

它似乎没有读取 JAR 内的 features 目录。

Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });

如何通过 cmdline 参数指向 JAR 内的 features 目录？

Answer 1

您将相对路径传递给了 Cucumber src\main\resources\features。因为您正在执行 Jar，所以该相对路径将使用当前工作目录转换为绝对路径。但是，由于 src\main\resources\features 是功能的源文件夹，因此找不到任何内容，您将得到:

Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features

相反，您必须告诉 Cucumber 您的功能位于类路径上。您可以通过以下方式执行此操作:

"classpath:features"
